This was an issue with the rollout of AD 2009 over the weekend. Everything should be fixed now. You may have to reset your Impulse data. To do this:
-Click the blue Stardock Logo in the upper left
-Choose 'Preferences...'
-Click on the 'Folders' section on the left
-Click the 'Reset Data' button
-Close impulse and relaunch it. You may notice a long update time, which is normal as it is rebuilding the deleted info.
You may also have to remove the incorrect registration by going into your Impulse registrations, right cliking on the Aquarium Desktop 2009 entry and remove it. Once you do this, hit F5 to refresh and relogin to Impulse, which should pull down the new, correct registration.
If ALL that fails, e-mail us at support@stardock.com. Make sure to reference this post if you do.
